BFC - Black FIRE Cement 1250°C

Cumple con lo anunciado. Buen producto. Lo he utilizado para sellar el tubo chimenea de una estufa de leña y no se escapa nada de humo. Es fácil de usar.

Utilisé pour recoller les parois intérieures en matériau réfractaire d'un poêle à bois. Réparation effectuée sans problème. Pour l'instant tient parfaitement à la flamme.

I actually needed a heat resistant black GROUT for a hearth (ie a horizontal surface). Problem is that no-one makes one - insipid sandy brown or grey is all that's available. I wondered whether the black fire cement might work - though fire cement often requires high temperature (900+ oC) to fully harden it. Firstly, to give some perspective, we're in Covid Pandemic Times! I contacted the company (that manufactures the various products) with a couple of questions about the company's HT tile adhesive and black fire cement's usefulness as a grout (see my other review), waited 5 days and received answers to (irrelevant) totally different questions! More perspective ... the questions you ask go to the Sales team; there's no way to ask the techy team a question and during this difficult time, the techy team may not have been available. I set up a couple for experiments of my own (I'm a chemist/scientist by genetics and training) and found that the cement could be used as grout - after a couple of hours with no excess heating - it fully set and even with hard rubbing with a damp cloth no black staining transferred! It's very easy to apply out of the tube, though quite runny (not a problem on a horizontal surface). However, after a few days the cement turned white! A quick rub with a damp cloth changed it back to black ... after a handful of repeats (hoping that whatever was leaching through would finally be gone I used an indelible black felt tip to stain the cement; It's still black after several months - problem solved EDIT: the 'indelible' black pen ( made for paper etc) fades somewhat after several months of being heated by the coal fire!! - It only takes a few seconds to reapply so on balance I am very happy with the cement.
